What happens when a space shuttle reenters the atmosphere?
Answer:
Although it causes drag, it also causes intense heat. Specifically, shuttles face intense temperatures of about 3000 degrees Fahrenheit (about 1649 degrees Celsius) [source: Hammond]. Blunt-body design helps alleviate the heat problem.

A scientist crossed a tall pea plant with a short pea plant. Of the offspring, 13 were tall and 12 were short, write the ratio of each phenotype to the total number of offspring. Express the ratios as fractions
Answer:
Tall offsprings: 13/25
Short offsprings: 12/25
Explanation:
According to this question, a cross between a tall pea plant and a short pea plant gives rise to the following:
13 tall pea offsprings
12 short pea offsprings
This means that a total of (13 + 12) = 25 offsprings were produced by this cross. To get the ratio of each phenotype to the total number of offspring, we say the number of each phenotype (tall or short) / total offspring the produced.
That is;
Tall offsprings: 13/25
Short offsprings: 12/25
In percentage, this can be represented as:
Tall offsprings: 13/25 × 100 = 52%
Short offsprings: 12/25 × 100 = 48%

In guinea pigs, the allele for a smooth coat (S) is dominant over the allele for a rough coat (s). Explain how you could find out whether a guinea pig with a smooth coat is a hybrid or a purebred.
Answer:
Explanation:
First of all you need to have ss because this is recessive.
Secondly there is 2 option for Dominant one
It could be Ss or SS so if you wanna know what is what you need to use recessive gen
S- ss if all genes are hybrid dominant one would be SS if some genes aren’t hybrid dominant one would be Ss

which part of the amino acid most likely contributes to the hydrophobic behavior if this region in the polypeptide
Answer:
This question is incomplete
Explanation:
This question is incomplete, however, the side chain is usually the part of an amino acid that is either hydrophilic or hydrophobic in nature. When the side chain has little or no polarity (i.e they lack the ability to interact with highly polar water molecules), the amino acid exhibits hydrophobic properties. Hydrophobic (water-fearing) substances are substances that do not interact/dissolve in water.
